Materials 🔨

Question 1

Stiff

Answer 1

Large young’s modulus, large stress required for small strain

Question 2

Define ductile in relation to materials

Answer 2

Can undergo a large amount of plastic deformation before breaking

Question 3

Define tough in relation to materials

Answer 3

Requires a large amount of work done to break

Question 4

Define strong in relation to materials

Answer 4

Can withstand a large stress before breaking, high ultimate tensile strength

Question 5

Define hard in relation to materials

Answer 5

Can withstand impacts to the surface without dents or scratches
